Default Picoblaze C Compiler

Hi all,
On www.poderico.co.uk you can download the free C compiler for
Picoblaze version 1.7.7
In the next 2 months the optimizer should be ready and the code
generated will be shorter.
I' wish to design the debugger too.
Any help and suggestions is welcome.

Francesco

Binary only?
Windows only?

Looks impressive.

Have you also looked at the quite similar ( but open sourced )
Lattice Mico8,
http://www.latticesemi.com/products/...ollermico8.cfm

and also the PacoBlaze ?
http://bleyer.org/pacoblaze/

In the examples section, you could add the output files,
with the source, so users can easily see the code generated ?

Yes I had a look at Lattice Mico8,
but to be honest at work I use only Xilinx...

I think Pacoblaze is compatible with picoblaze,
so you can use the compiler with pacoblaze in any FPGA.

OK I will do.

Does anybody know how to read/write the BRAM using the JTAG?
I need this to design the debugger....

Thanks all you.
Francesco

FWIR, when I looked at them both, the Mico8 lacked the
Return with Flag option, and the Mico8 looked to have
an easier way to extend the JMP/CALL, to allow
larger code. [which will matter to C users ]
- ie when doing a compiler, look at allowing different
call sizes, as legal/error, and some simple means to
modify the opcode generation to match that detail
of the core.

I think there are some (optional) extensions in PacoBlaze,
that could make sense to support in a compiler.

Hi Francesco,

Thanks for your effort,

Take a look at the following article for accessing jtag port in a user
design.

http://www.xilinx.com/publications/x.../xc_jtag53.htm

Best regards,
Alper YILDIRIM
